Screen lock - Prevents any settings changes; cancels when an alarm initiates b. Alarm Silence - Silences Alarms for 2 minutes; cancels when an alarm is initiated c. Accept - Key that accepts ventilator settlings changes d. Clear - Clears proposed settings changes e. Expiratory pause -Used to measure intrinsic peep measurement of Total PEEP - Set PEEP = Intrinsic PEEP f. Rotary Encoder - Used to raise or lower settings 4. Explain the IBW - Means Ideal Body Weight: used to set initial patient settings on ventilator startup. This helps to insure correct patient settings on ventilator startup whether a child or adult is to be ventilated. What happens after POST when the patient circuits and test lung are attached? Safety PCV - We don’t want to ventilate inappropriately What happens if a piece of paper is taped over the GUI screen for any length of time? Device Alert - Blocked Touchscreen What is the key entry sequence for making simple ventilator settings change? Press buttons, turn encoder, accept. What is the key entry sequence for making a batch change? Touch button, turn encoder, touch button, turn encoder, touch button, turn encoder, etc., Proceed, Accept. What other param
